Abstract

L'invention concerne un procédé permettant de concevoir une ou plusieurs impulsions radiofréquence (RF) multivoie, multibande destinées à être utilisées avec un système d'imagerie par résonance magnétique (IRM). Le procédé consiste à déterminer un nombre de modulations d'amplitude RF et un nombre de modulations de phase RF pour chaque voie d'une bobine RF multivoie, par réduction à un minimum d'une fonction objective qui comprend un vecteur de valeurs complexes. La fonction objective contient aussi une matrice système prenant en compte à la fois un profil de sensibilité spatiale de chaque voie d'une bobine RF multivoie et une carte de champ magnétique pour chaque bande d'excitation de l'impulsion RF multibande.
